Cardiovascular reactivity, anxiety and anger during perceived controllability.
The purpose of this study was to investigate the relationship between emotional and cardiovascular responses in an aversive active coping situation. A letter detection task was presented to 64 male students. From a stream of letters scrolling over a screen, subjects were required to eliminate specific letters. Task difficulty was varied by changing the speed with which the stream moved along on the screen. Perceived control over an aversive loud tone was manipulated by instruction. While blood pressure differences in the experimental conditions could not be found, the group with perceived control displayed greater increases in heart rate and greater shortening of pulse transit time. In subjects low in trait anger, belief of control over aversive tones led to heightened cardiovascular reactivity compared with subjects high in trait anger. The results are discussed with respect to suppression of anger and a possibly opposite effect of emotion and mental effort in aversive active coping situations.
